一、概述在炼油厂内锅炉蒸汽系统与加热炉的能耗占全厂能耗比例相当大,降低这两个方面的能耗应是炼油厂节能的主要任务。目前国内所采取的措施,如利用油品余能加热锅炉给水,锅炉加热炉燃用热渣油,降低加热炉排烟温度(采用空气预热器),降低加热炉燃烧的过剩空气系数等均是以提高锅炉及加热炉的热效率入手的。目前效率较高的锅炉,热效率已经达到91～92%,加热炉的热效率
I. Overview In the refinery boiler steam system and heating furnace energy consumption accounted for a considerable proportion of the whole plant energy consumption, reduce energy consumption in these two aspects should be the main task of the refinery energy conservation. The current domestic measures taken, such as the use of oil can still heat boiler feed water, boilers burning hot residual oil, reducing furnace exhaust gas temperature (using air preheater), reducing the furnace combustion excess air coefficient Dengjun Is to improve the thermal efficiency of boilers and furnace start. At present the boiler with higher efficiency, thermal efficiency has reached 91 ~ 92%, the heating furnace thermal efficiency
